I Die Alone.

American pacifist Private Finch (Carl Schreiber) finds himself pressured by his superiors to kill a P.O.W. captured from battle. As a direct result of his apprehensions, a fatal confrontation explodes amongst his platoon, and Finch becomes stranded behind enemy lines armed with nothing but limited ammunition and an uncertain sense of direction. Making his way through foreign soil, he encounters a mysterious mailman (Marc Litman) anxious to throw himself into battle. But on their exhausting quest to find a radio and signal for help, it becomes clear that Finch's new friend harbors a few dark secrets that could prove more threatening than the next ambush.
